Let 
be the dimensions of the rectangle. We know the equations for both area and perimeter:
So, we have the following system:
From the second equation, we can deduce
Plug this in the first equation to get
Refactor as
And solve with the usual quadratic formula to get
Both solutions are feasible, because they're both positive.
If we chose the positive solution, we have
If we choose the negative solution, we have
So, we're just swapping the role of 
and 
. The two dimensions of the rectangle are 
and 
Answer:
A quadrilateral is a polygon with four sides.
Practicly anything with 4 sides like square, Rectangle ,and rhombas
Im sorry if i didn't answer your question but i did not get what you were saying but here is an image that can maybe help you
Answer:
Step-by-step explanation:
You first have to draw a line
And like a ratio. _1___2______
75. 150
6/10 rounded to the nearest tenth inches a hour of rain fell
Solve for x over the real numbers:
x^2 = 49
Take the square root of both sides:
Answer: x = 7 or x = -7
